Product Description

The MagnaFlow 16829 Street Series Cat-Back Exhaust System is a direct-fit, bolt-on performance upgrade engineered specifically for 1983-1992 Chevrolet Camaro and Pontiac Firebird V8 models - including the Z28, IROC-Z, Trans Am, GTA, and Formula trims running the 5.0L (305ci) or 5.7L (350ci) V8. Built from fully mandrel-bent 3-inch 409 stainless steel tubing, this system eliminates the restrictive crush bends of the factory exhaust to unlock improved exhaust flow, resulting in dyno-proven gains in both horsepower and torque. The straight-through muffler design is what MagnaFlow is renowned for - producing a deep, smooth, resonant tone that sounds aggressive under throttle without being intrusive at cruise.

Installation is bolt-on using OEM-style mounting locations and hardware, made possible by MagnaFlow's use of 3D scanning technology during the development process to ensure precise fitment on the third-generation F-Body platform. The included over-axle pipe, dual-outlet muffler, and 3.5-inch polished round tips are all pre-assembled and include all necessary hardware for a DIY-friendly install. Note that exhaust tip protrusion past the rear bumper is a known characteristic of this system; some owners choose to modify the tip angle or trim to preference. Professional installation is recommended if modifications are required.

Backed by MagnaFlow's limited lifetime warranty and proudly manufactured in the USA using CNC robotic precision welding, the 16829 is the ideal upgrade for any F-Body enthusiast looking to revive or improve the performance and sound of their classic Camaro or Firebird. The system is 50-state emissions legal as a cat-back replacement (installs behind the factory catalytic converter), making it a compliant and practical performance upgrade for street-driven builds.
